What is the ultimate fate of the electrons that are stripped from glucose during cellular respiration?

Cellular respiration is a process that involves use of glucose to generate energy in form of ATP that is then used for cellular activities. The process takes place in the mitochondria which are organelles in a cell.  Glucose is broken down through glycolysis and the citric acid cycle which results in the yield of energy in form of ATP. However, most of the energy is derived from the electrons carriers such as NADH and FADH2. The electrons stripped of glucose are then used to generate water molecules in the end of the process.
